One portion is how many grams?

(I've read through one page of the links you offerred. However, those foreign web page showed very slowly here, because stupid and insane Chinese filter put its nose into it to check out anything that I could not open another link)

Thank you both.

Forty two pounds are only expressed as ￡42?

1. Forty-two UK pounds is a sum of money. Sums of money, weights, distances, (and other things as well) are "singular quantities".

2. Forty-two pounds (the hyphen is often seen in UK English) can be expressed as £42 but in accounting and when it is desired to be precise e.g. when writing a cheque we write £42.00.

3. A sum of money under one pound such as forty-two pence can be written causally as 42p but as before, it is more precisely written as £0.42.

Thanks

A portion of vegetables may not be a specific weight--for example, if you want to get iron in your diet, eating one leek will do the trick for you, but you could ten pounds of beans and not get enough. You want a variety of different vegetables and different types of vegetables to get the nutritonal value you need. The United States Department of Agriculture, for a variety of reasons, gives one half cup as the portion size for fruits and vegetables. How much it weighs is meaningless--a cup is a measure of volume. One half cup is about 115 mililiters.

So five portions a day are about 0.6 kilogram of fruit and vegs a day?
That hits the point surely.
Thank you.

Different items of the same volume are not necessarily the same weight, so the reference to weight is nonsensical when volume is the measurement.

@oristarA,

No, that's not what it means at all. Which weighs more, 115 mililiters of water, or 115 mililiters of sand? The common expression in English is that you're comparing apples to oranges. In this case, you comparing measures of weight to measures of volume.

I'm right, Set and EhBeth.

My comparison is a short-cut to clear the barrier for understanding, like adding an auxiliary line to a puzzling geometric figure to make it easy to solve.

Remember: We are talking about portions of fruit and veg, not anything else, so your comparison with sand is an ungrounded aberration. And EhBeth has ignored the fact that common fruit and vegs share almost same specific gravity! You can make an apple into a cup of juice, and get an impression: their weight is about equal to their volumn.
